Had initial phone screening with an HR rep focusing on basic questions like why I'm looking to make a move, my background, and to describe my most difficult technical challenge and how I overcame. The HR rep seemed satisfied with my answers and ended the call by saying next-level interviews with the potential hiring managers would be setup in 1-2 business days. 1 week later she called my recruiter to say they won't be proceeding because I didn't provide enough technical details in my answers. Very odd--one typically doesn't go into depth at an initial HR screening and you'd think they'd ask for more depth if they want it.
